Abstract
A crank and rocker combined type testing jig capable of adjusting elevation angles of antennas comprises an external rotatable testing device, a crank, a movable slider, an antenna support and an angle gauge. A test antenna is fittingly placed on the antenna support, one end of the antenna support is rotatably arranged on the external rotatable testing device, and the other end of the antenna support is a free end; the angle gauge is arranged on the antenna support, and a linear grooved guide rail is arranged on the antenna support; and one end of the crank is rotatably arranged on the external rotatable testing device, and the other end of the crank is movably sleeved on the outside of the linear grooved guide rail on the antenna support via the movable slider. The crank and rocker combined type testing jig has the advantages that a link for adjusting elevation by the aid of a triangular support is omitted, and the workload is reduced to a great extent; the elevation angle positioning precision is improved owing to a crank and rocker mechanism; and the crank and rocker combined type testing jig is low in part consumption and cost and simple in structure, and is portable.
Description
Technical field
The present invention relates to a kind of adjustment testing jig, especially relate to a kind of testing jig being realized that by crank and rocker mechanism antenna level, pitch attitude are adjusted, the antenna measurement frame in angle conversion process, antenna attitude being had to level or luffing angle requirement in external test arrangements perpendicular can be adapted to.
Background technology
At present, in laboratory, the testing jig basic condition that measurement of magnetic field device uses is: based on tripod, when needs carry out pitching adjustment to antenna level, needs to position with some simple survey instruments such as rulers and put; Or utilize three of tripod length that leg stretches out to adjust.Above-mentioned testing jig has following defect: 1) in the process of adjustment, need many people to operate; 2) can introduce new test error when adjusting triangle frame supporting leg, bring workload to a certain degree to antenna measurement, measuring accuracy is also difficult to ensure simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of crank rocker combined type luffing angle adjustment antenna measurement frame; This testing jig is for current proving installation Problems existing, devise crank rocker combined type luffing angle adjustment rack, can adapt to have level or luffing angle requirement to antenna attitude in angle conversion process in external test arrangements perpendicular, improve angular adjustment precision and work efficiency.
For solving the problems of the technologies described above, the present invention adopt following technical scheme:
Crank rocker combined type luffing angle adjustment antenna measurement frame, comprises outer rotatable proving installation, crank, moving slider, antenna holder and inclinometer; The placement test antenna that described antenna holder can mate, one end of described antenna holder can be rotatably set on outer rotatable proving installation, and the other end is free end; Described antenna holder arranges inclinometer, can be determined the horizontal tilt angle of antenna holder by inclinometer, thus determine the horizontal tilt angle of antenna, described antenna holder is provided with horizontal straight line dead slot guide rail; One end of described crank can be rotatably set on outer rotatable proving installation, and the other end is by outside the moving slider straight line dead slot guide rail being set on antenna holder movably; Make moving slider can linearly dead slot slide.
Preferably, be provided with antenna holder turning axle outside one end of described antenna holder, outer rotatable proving installation is provided with antenna holder rotating hole, antenna holder turning axle can be rotatably set in antenna holder rotating hole; This structure can make antenna holder turning axle rotate freely in antenna holder rotating hole, and namely whole antenna holder can rotate freely along antenna holder turning axle.
Preferably, one end of described crank and outer rotatable proving installation rotatable fixing by pin; The other end is provided with through hole, and described moving slider is provided with two fixed orifices, is arranged on movably in straight line dead slot guide rail by moving slider through the through hole on fixed orifice, straight line dead slot guide rail and crank by pin.
Preferably, described antenna holder is provided with two antenna stationary shaft, and test days line card can be established wherein by this antenna stationary shaft.
The present invention has following beneficial effect:
